      DCM and Tap Water  Bookmark   

A simple question - Will tap water contaminate DCM making it unsuitable for extracting your goods (i.e. epoxides, ketones)? BOB is distilling Zap Strip by simply boiling it out of a flask into a container full of ice cubes made from tap water. Kindof a dumb question but just want to play it safe(and BOB too lazy to go to the damn gas station to get distilled ice cool).

Would the cl in the tap water not go into the dcm possibly fouling something.?

      No. Chloride ions are not soluble in DCM.  Bookmark   

No. Chloride ions are not soluble in DCM. Just dry the DCM over baked epsom salt and filter, and everything is set.

Is Chlorine soluble in NP's and water?

RU using a full destilling set up ? I haven't heard of using ice inside the receiving flask. Maybe in a bucket which the receiving flask sits in, but not in the flask? Pls elaborate.

      Why dry DCM?  Bookmark   

If your DCM is going to be used for such purposes as extracting oils from aqueous solutions, why even bother to dry your DCM?

      Distilling  Bookmark   

Lacking proper distillation equipment, BOB simply distill dcm from a certain brand of paint thinner (*Zip Strop) by boiling it out from a flask with copper tubing at the top, the tubing thence leading the vapors to a jug full of ice where the DCM, with such a low boiling point (48 celsius ) quickly condenses, forming two layers: DCM at the bottom and melted ice at the top.

Hay "stranger"! Someone recently tried that method and it
seemed to work pretty good! Saves alot of cleaning.
Fry daddy on a variac with 50-60C hot water, and the stuff
plus some acetone was coming over real fast. Into the
sep funnel, and voila!

CG I miss you sweety, I really do.

Swim will never use an extraction solvent besides DCM again.
Too much bullshit.

But DCM doesn't work for everything

Those who give up essential liberties for temporary safety deserve neither liberty nor safety

      don't use it for gassing  Bookmark   

MDMA and meth are both soluble in DCM.  That doesn't make it a good solvent for extracting tertiary amines with.
